quality or not.. its asking alot of a urethane product to holdout over 80grit to primer to paint.. keep in mind most of 2k primers are used in crash shops.. what shop in there right mind would primer over 80 and have 80 grit scratches into oem paint.. thats just asking for problems.. the bare minimum to most is 150.. i prefer 180 da and have no problems hitting and feathering with 320 and hitting mud with that for a crash style repair.
